Alloy



Patented Dec. 29, 1931 VICTOR WYLDES, OF TORONTO, ONTARIO, CANADA ALLOY1V0 Drawing.

The invention relates to the production of an alloy which simulates goldboth in appearance and characteristics, and mainly consists of thehereinafter described manner of compounding.

The ingredients employed in this process are as follows:

Pure alcohol 1 ounce The proportions given above are those preferred;variations may of course be resorted to still within the spirit andscope of the invention. The tin content also may be replaced by someother metallic chemical equivalent, such as zinc. Dry yeast may besubstituted for magnesia. The effect, however, of substituting zinc anddry yeast is that the resultant alloy is somewhat harder.

Tn carrying out this process, the'copper is first melted in a. crucibleor. the like and heated to twelve hundred degrees centigrade, the otherconstitutents being added in the order set forth in the herein formulaat an interval of two minutes between the addition of each ingredient.The massis mixed for minutes and then boiled for minutes, the cruciblebeing covered during boiling. The resultant alloy is subsequently pouredinto a mould and allowed to air-cool for half an hour following which itis immersed in clean cold water.

It may be stated that the use of fullersearth serves the double purposeof making the ingredients cohere and for coacting with the borax inlightening the colour of the alloy; the borax, of course, constitutingthe principal bleaching agent. The magnesia both clarifies andrefines'the compound. The white precipitate (ammoniated mercury)accelerates amalgamation. The alcohol is introduced by reason of itstendency to impart lustre to the alloy, but may be omitted whenever ahigh degree of brilliancy is not required. Tin, as well known, produceshard- Application filed December 5, 1929. Serial No. 411,991.

ness, whilst additionally it aids in lightening the colour of the alloy.However ,for this latter purpose other white metals might be resortedto.

According to this process and method of compounding, an exceedinglylustrous metal is produced simulative of gold. It not only possesses thesame physical properties, such as malleability and ductility but isfound to have an even more desirable characteristic in that like gold itis immune from tarnishing. The possession of the above characteristicsand the fact that this simulative gold can be produced cco omicallyrenders it admirably suited for substituting gold in the manufacture ofjewelry, and extend its use to such articles as name-plates, hand-rails,door handles, and many other articles where the high cost of goldpractically prohibits its use.

What I claim is:

1. A process of producing an alloy of the class described consisting inmelting 5 lbs. 10 ozs. copper, successively adding 3 ozs. fullers-earth,7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin, 3 ozs. magnesia,and agitating the mixture.

2. A process of producing an alloy of the class described consisting in{melting 5 lbs. 10 ozs. copper, successively adding 3 ozs.fullers-earth, 7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin, 3ozs. magnesia, and 1 oz. alcohol, and mixing and boiling the mass.

3. A process of producing an alloy of the class described consisting inmelting and heat- 8 ing 5 lbs. 10 ozs. copper to about twelve hundreddegrees centigrade, adding successively at two minute intervals 3 ozs.fullers-earth, 7 ozs. borax, 3 ozs. white precipitate, 12 ozs. tin,

3 ozs. magnesia, and 1 oz. alcohol, mixing the resultant mass for aboutthirty-five minutes, and boiling it for about forty minutes.
